    Great, now we can have traffic but on these old rails.

    How about, and I know this is a radical idea, actually fixing up the old rail lines and putting trains on them instead of this gimmick?

      Old railway lines in Europe often aren’t complete anymore and only cover relatively small distances.

      There simply isn’t enough infrastructure to handle a full train network and fixing them up would probably require existing infrastructure and buildings to be disowned and destroyed.

    Yes Louis Brennan designed a gyroscopic monorail in the early 1900’s but there’s a reason it didn’t work out. Every car needs its own gyroscope which is a lot of dynamic components that need maintenance. A regular two rail train is much simpler and cheaper to operate. The idea these techbros have that everything is made better with individual pods is pretty wasteful when we already have better and cheaper solutions to virtually every problem they have tried to invent for us. Are we even super concerned about rural folks taking transit? By definition they are a small portion of the population and have the greatest need for personal transport. Where we need transit adoption is in urban areas with large populations who all want to drive their personal 2 tonnes of plastic and steel right into town and park it (for free obviously) in their own little parking space.

    A gadgetbahn like this will only serve a limited population and won’t be able to tie into the existing transit network. There might be niche situations where it’s not a terrible idea but it is not a good generalized solution.

      I could see those as an option for rural areas without much traffic. A full train might not be economical, but a small pod is. It could transport people to the closest proper train station where they can hop off.

      But that would mean you’d have to maintain a ton of tracks for a handful of people.

        Connect them together for efficiency, and maybe use both rails for stability and to reduce design conplexity. (you dont even need any additional infrastructure!) Also, have them arrive regularly, so that users don’t need to bother with an app! Brilliant!

        Seriously though, it’s really amazing how people keep inventing trains but worse. I guess this idea makes some sense if there aren’t enough riders for regular train service, but still…

      Read the article, that’s literally the first thing they explain

      Besides which, it’s very obviously a train if you just look at it. It’s a small monorail train specifically designed for this purpose using existing infrastructure.

      People are never fucking happy.

        A train is a collection of rolling railcars propelled by one or more locomotives. These are individual self-powered railcars.

        So no, there’s no train here. Just monorail pods that will get congested as density increases.

        The whole concept of a train is that all the cars move together and the only congestion is at the switching yards, where it can be optimized.

          These pods are only used on rails with very low ridership. They would switch to a train if ridership increased.

          Look at it this way: you can have a train that has a capacity of 100 people, but it only runs once a day due to the low demand, and only 2 people want to ride it at that time of day…Or you can have 10 pods, which do not require as much railway maintenance, and they can carry the 10 people who actually want to use this railway, completely on demand.

          Yeah, a train is better if you want to move ten thousand people a day at peak hour. But this is a cheaper way to move ten people at different times across a day. And it’s a cheaper way of inducing the demand that would justify the more efficient kind of expansion.

          Isn’t it better to have a train that runs when you want rather than having to wait potentially hours for the scheduled commuter train. Isn’t this better?

      FUCKING DOING OUR JOB AS TRANSPORT MODELLERS AND DOING A FUCKING COST BENEFIT ANALYSIS THAT SHOWS YOU’RE NEVER GOING TO GET FUCKING MODE SHIFT FROM RURAL USERS UNLESS YOU RUN A FUCKING METRO STYLE 10 MINUTELY SERVICE WHICH IS FUCKING UNFEASIBLE WITH THE FUCKING RESOURCES WE HAVE AVAILABLE.

      IN THE FUCKING UK WE HAVE A LARGE NUMBER OF FUCKING ABANDONED RAILWAYS FROM THE PERIOD OF FUCKING COAL MINING THAT WOULDN’T HAVE ANYWHERE NEAR THE FUCKING DEMAND NECESSARY TO JUSTIFY SETTING UP AN EXPENSIVE AS FUCK SIGNALLING SYSTEM TO BRING THEM UP TO MODERN FUCKING SAFETY STANDARDS, ALONGSIDE REPLACING THE FUCKING RAILS, SLEEPERS AND BEDS.

      IF INSTEAD YOU CAN HAVE A FUCKING PUBLICALLY OWNED FLEET OF FUCKING ELECTRIC ‘MINI TRAINS’ THAT PEOPLE COULD USE FOR INFREQUENT BUT NECESSARY TRIPS, THAT COULD REMOVE A FUCKING SIGNIFICANT BARRIER TO MODE SHIFT, WHICH WOULD BE PRETTY FUCKING RAD

      Trains are expensive to run if you don’t have enough passengers (like in small villages).

    I would love a mini rail system like this in my community.

    Actually, I’ll take most any public transportation at this point.

    The Brennan monorail rides again!

    Some of this technology may sound a bit “over-ambitious,” but keep in mind the project was inspired by a fully functional self-balancing monorail that mechanical engineer Louis Brennan designed and demonstrated back in the early 1900s.

    Seems over-complicated…

    I could imagine an autonomous, on-demand rural train service. Due to the low expected traffic, it seems like you could just build some additional sidings and use a more conventional design.

      How would traffic pass each other? You would be stuck with the same issue as normal trains.

          If someone was willing to invest into building and maintaining infrastructure there would be no need for this concept, but that’s a political issue. The idea of this concept is do make the best of what you have.

    I’m cautiously optimistic about this, it seems like an okay idea and the fact that they have vehicles working on a test track IRL means it’s at least not an obvious scam like hyperloop.

    Also the fact that they have a specific use case in mind, don’t say it’s going to revolutionize all transportation, and are reusing existing infrastructure, all bode well.

      The crane is the part I don’t get. Is it a stationary crane? Is that not more work than just putting a track switch in place instead?

        It’s only for the alpha-test vehicles. The crane does not touch the rails, it’s a security issue for testing e.g. min power gyro

        The problem is that the wheels have flanges on both sides, so I don’t think switches work.

        The best solution would be a loop connecting the rails at each end, but that’s obviously not compatible with running regular freight trains since it would need to be switchless.

        Thus presumably they need to be externally flipped around and moved, for which I’d guess a crane like those used for moving containers on and off trains is ideal.

        With a crane they could also easily move the vehicles to a storage area so freight trains can pass through.

    However, what if it were possible to hail a small electric vehicle right when you needed it – via a taxi- or Uber-style app

    Uber style app. Seriously, fuck no. Send trains or don’t, fuck Uber and their business model.
